HAL_PX4: new buffered storeage driver for microsd cards
...
this does all IO in the timer thread, avoids writes that don't change
data, and does all writes in multiples of 128 byte chunks. This should
be about as friendly to SD cards as we can get.

HAL_PX4: rewrite UART driver to be much more efficient
...
this does the IO in the timer thread, and uses buffers in the main
task to avoid system call costs in the flight code.
The cost of PX4 read and write system calls is quite high - about 10
to 15 usec. We can't afford to pay that per byte

Add AVR compatibility header for missing math.h definitions.
